I've got a vintage gem yamaha southern jumbo style acoustic (fg-300)... hummingbird, dove, songwriter deluxe etc. I just procured this guitar off craigslist and its GREAT for fingerpicking and pretty decent for folksy stuff, but I want to make it just a little more responsive with bass and and just a deeper overall tone. My current theory is to raise the very low action... the geet has an adjustable bridge (which is pretty cool, if not quirky)... so would raising the action make the guitar a little bit louder and boomier??? still want to keep it with a gibson vibe, but a little bit of a bigger sound. is raising the action a good idea?? what other options do I have to open up the sound a little bit?
